Got B12 check a year ago and it was 300 have been on B12 injections and last check above normal range which is okay. It was my neurologist that started the B12 also take B6 and folate. Was on metanex I believe that is the correct spelling was costing over $65 per month since insurance will not cover it. I believe it was your site that talked about alternative to the metanex. Been a guest on this site for a year but decided I needs some help with the new issue.
